Vedclass · Answer

(D) The characteristics are analyzed as follows:$(i)$ Sickle-shaped $RBC$ is a hallmark of sickle-cell anaemia (autosomal recessive).$(ii)$ Non-stop bleeding due to lack of clotting factors is characteristic of haemophilia ($X$-linked recessive).$(iii)$ Haemophilia is $X$-linked recessive; thus,a heterozygous female (carrier) transmits the disease to her sons.$(iv)$ Sickle-cell anaemia is autosomal recessive; thus,both heterozygous parents (carriers) can transmit the disease to their offspring.Therefore,$(i)$ and $(iv)$ correspond to sickle-cell anaemia,while $(ii)$ and $(iii)$ correspond to haemophilia.

Identify the genetic disorders based on the following characteristics:
$(i)$ Presence of sickle-shaped $RBC$.
$(ii)$ Blood does not clot,leading to non-stop bleeding.
$(iii)$ The heterozygous female transmits the disease to sons.
$(iv)$ Both heterozygous parents transmit the disease to offspring.
